Answer:

Two homologous chromosomes paired together, each of which has two sister chromatids.

Explanation:

Zygotene stage of prophase I of meiosis I is characterized by the pairing of homologous chromosomes with help of synaptonemal complex. Since DNA replication has occurred in S phase, each chromosome in the pair contains two sister chromatids.  

So, the chromosome pair appears to have a total of four chromatids and the structure is termed as "tetrad".

Answer the questions plz
exis [7]

Answer:

1) A double Helix with complementary bases in the middle. The backbone is made of sugar and phosphates. The middle is bases

2) To hold the genetic info for the cell

3) To bring the genetic info from the nucleus to the ribosomes as DNA can't leave the nucleus

4) To bring amino acids to the ribosomes to help build a protein

5) A chain of amino acids held together by peptide bonds

6) Ribosomes

7) Because those are the bases that are complementary in DNA so they must be equal

8) It could lead to a mutation as it would cause the mRNA to code for a different amino acid and thus a different protein will be made

9) DNA is the blueprint for mRNA which will travel to the ribosomes and code for specific amino acids which will eventually build a protein
