Answer:
In humans and other mammals, biological sex is determined by a pair of sex chromosomes: XY in males and XX in females. Genes on the X chromosome are said to be X-linked. X-linked genes have distinctive inheritance patterns because they are present in different numbers in females (XX) and males (XY).
Explanation:
Answer:
e. carpel and stamen is the correct answer.
Explanation:
- The reproductive parts of an angiosperm are the carpel and stamen.
- Angiosperms are the flowering plants that bear seeds.Examples of angiosperms are: Apple, Brinjal.
- The stamen function is to produce and it is a male reproductive structure.

- Stalk
- Carpel function is to produce egg cells and to protect the developing embryo and it is female reproductive structures.
- Carpel has three parts:
- stigma
- Style
- Ovary
The answer is D. Always true in all places
Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called Non-histone protein.
The proteins that remain after the histones have been taken out are known as non-histone proteins. A large group of heterogeneous proteins referred to as non-histone proteins organise and compress the chromosome into higher order structures.
They play a crucial role in regulating processes such nuclear transport, steroid hormone activity, nucleosome remodelling, DNA replication, RNA synthesis and processing, and the transition between interphase and mitosis.
Scaffold proteins, DNA polymerase, Heterochromatin Protein 1, and Polycomb are examples of typical non-histone proteins. This classification area also includes a large number of other structural, regulatory, and motor proteins. Non-histone proteins can be acidic. Other than histones, many proteins have the ability to bind to DNA and change the shape of the chromatin by means of epigenetic processes.
